all attempts to associate physical properties with it are bound to fail. Aether is the seat of a stationary system of waves. These stationary waves are formed by the super position of sinusoidal variations in the properties of the medium. In the language of Jaina Šāstras it is called sadgunita-hani-vrddhi and its minutes details are given in the
text. (iii) Science did not believe in the atomicity of space until lately,
but now the view is that the space is composed of a huge number of very small (but finite) unit cells which cannot be sub-divided in any way. These unit cells are called pradeśas
in the language of our sästras. (iv)to(ix) Read page 7 of the Preface to the First Edition. (x) The existence of nuclear matter follows directly from the
definition of pradesa and in recent years it has been con
firmed by the discovery of Quasars. (xi) In the last few years an intensive hunt has been going on all
over the world for the search of the 'ultimate particle of matter called pudgala by the Jains and Quark by the scientists. The Quark in the building block of matter out of
which every thing is made. (xii) Scientists are of opinion that all processes of life can be
explained in terms of the laws of physics and chemistry. According to them the proteins, the DNA and RNA are the substances which govern all activities of life. Hundreds of experiments were performed in America and elsewhere to correlate these substances with consciousness and memory but they badly failed i.e. consciousness could not be explained in terms to physics and chemistry and hence the existence of soul remains
unchallenged (vide sutra 4). I offer my profound thanks to Jain-Ratna Seth Shital Prasad of Meerut who took keen interest in the progress of the work from time to time. He has done his best to ameliorate the condition of Jain Samaja.
As I cannot read and write myself owing to bad eye-sight, Shri Mool Chand Jain of C.D.A., Central Command, Meerut did the entire work of preparing the manuscript. I sincerely feel that with
